<p>A high temperature membrane reactor or gas purification apparatus (10) includes a housing (12) containing a gas heating chamber (20) and a gas extraction component, preferably one or more tubular membranes (22). A surrounding annulus (24) provides heat exchange and insulation by circulating a mixed gas flow about housing (12) and then injecting the mixed gas flow into housing (12) for extraction or reaction. Apparatus (10) further includes an outlet (34) for releasing raffinate including a flow controlling restriction (38). Heating is provided by conducting the raffinate from the gas extraction component (22) to heating chamber (20) wherein reaction with catalyst (42) generates heat. A preferred application is for extracting hydrogen from the mixed gas flow or for generating hydrogen, e.g., by reforming methanol, ethanol, or gasoline. These features, alone or in combination, provide better energy management, better flow management, and better safety than current designs.</p> |
